Just a quick message: I have added Ruby Enterprise Edition to the Portage tree, ready for the adventurous to test ;)

The package is in dev-lang/ruby-enterprise, but you'll need to unmask it first. To install rubygems, you should also unmask the ruby_targets_ree18 USE flag in /etc/portage/profile/use.mask.

The usual disclaimer: The package might still kill little bonsaikittens, so be careful!
Does it work? Does it not? Let us know: #gentoo-ruby on freenode as usual.
